UNITED STAT Pagans. OFFICE- WILLIAM DOUGLAS CARTER, OF QUINCY, ILLINOIS.

TELEPHONE-BOOTH.

To all whom it may concern:

Be it known that I, WILLIAM DOUGLAS CARTER, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented a new and useful Improvement in Telephone- Booths, cation.

This invention relates to a booth contain ing a door so mounted as to move inward on hinges, levers, or slides, so as to expel and entrain air from and into said booth, and to be so contrived as to close the doorway of said booth during the occupancy of same. This object is attained by the mechanism illustrated in the accompanying drawings forming part of this specification.

Figure 1 is a front and side view of a booth with top removed, showingmy ventilating door in the position which it occupies when the doorway to said booth is closed by said ventilatin door; Fig. 2 is a similar view of the bootii showing the ventilating door in one of the successive positions which it assumes when pushed inward a person entering the booth; Fig. 3 is a view of the same booth showing the ventilating door at the end of its inward swing, and about to return to close the doorway; Fig. 4 is a View of the booth showing the ventilating door in one of the successive positions which it assumes in returning to the original closed position shown in Fig. 1; Fig. 5 is an enlarged viewshowing the lever and bearings upon which said ventilating door swings; Fig. 6 shows amodified construction of the booth and ventilating door designed to illustrate the same principle shown in the above named drawings.

Similar figures refer to similar parts throughout the several views.

Ventilating'door l is supported between the bearings 2 and 3 at the ends of the arms 4 and 5, which arms themselves are carried on bearings 6 and 7 respectively.

8 is a stop so placed as to prevent arm 5 and ventilating door 1 from swinging outward when in the closed position shown in Fig. 1.

9 are knobs used to open the-door from the inside when the occupant of the booth is ready to leave the same. ()no of these knobs is always on the inside and one on the out side of saidventilating doon' 10 are rods connecting kno'is f) with levers 11 so as to release the catch 13 (shown in Fig. 5) and thereby permit the ventilating Specification of Letters Iatent.

Application filed October 18, 1910. Serial No. 587,756.

in Figs. 3

of which the following is a specifi- Patented 0015.29,].912.

door to swing on bearings 2 and 3 as shown and 4:. The releasing of this catch is newssary in order that the occupant of booth may open the door from the ins1 e. 15 are rollers fixed to the top of ventilating door 1, and so placed as to follow in the track or slot 16 and thereby control the movement of ventilating door 1 in closmg. In Fig. 5, 17 is a spring which operates to force lever 4: toward the front of the booth and into the position shown in Fig. 1.

Catch 13, Fig. 5 hinged at bearing 18, car-.

rice the lug 19 which engages .with post 20 just b ore ventilating door 1 reaches its extreme inward position, as shown in Fig. 3. Post 20 being mounted on the inside wall of the booth, forces upward catch 13 (see Fig. 5) and releases the ventilating door so that it can swing on bearings 2 and 3 (see Figs. 3 and 4.) ventilating door 1 outward from the side wall, therebystarting said ventilating door on its return path to close the doorway of the booth. The path of the ventilating door in closing, leaves space for the party within the booth to stand.

The end of post 20 presses Bearings (S and 7 are positioned a short way from the corners of the ventilating door shown so that the ventilating door will swing outward at the right hand edge, and thereby form the opening 21 (Fig. 2) to permit the egress of air from the booth when the ventilating door is forced inward.

The inside wall .22 of the booth is curved to fit n'ioreelosely the left hand edge of the ventilating door as it swings inward on bearings (3 and 7 so that the ventilating door will sweep through substantially all of the inside area of said booth, and thereby be more effective in expelling and entraining air from and into the same. 23 is a recess in said wall 22 for the purpose of holding a telephone or other apparatus out of the pathof the ventilating door.

lfiig. (1 shows a modified construction of the booth and ventilating door. In this figure the ventilating door merely revolves about the axis of its bearings 2 and 3. Leaf spring 24 operates to restore the ventilating door to its closed position bynieans of the pressure exerted against cam 25, whenever it is deflected from said position by a party entering or leaving the booth. The broken lines indicate one of the positions assumed by said door in its revolution.

The operation of my ventilating door is as follows: A party entering the booth presses against the outside knob or push plate and pushes the ventilating door inward 'on bearings 6 and 7. This forces the air within the booth out through the opening made at the right of the door, and at the same time draws into the booth a fresh supply of air through the doorway. lVhen and the catch 13' holds the arm 4 in place.

on thetop of the ventilating door, so that the above process may be repeated by the entrance of the next partydesiring to use the booth.

I claim:
